This thread is about my story also, I have the same inconclusive rising PSA after my RP.
3 Months after RP- PSA .06
6 mo out .16
6 1/2 mo out .19
3 weeks on Avodart .154
My Surgeon really believes my slow PSA increase was due to benign tissue left behind and that the reconnection of the blood system to the tissue is causing this slow rise. The decreased PSA after 3 weeks on Avodart confirmed that some or all of the PSA was generated by benign tissue.
He purposely left prostate tissue connected to my bladder. He decided that based on my path report and what he saw during surgery that he would not cut into my bladder and damage it but leave prostate tissue behind instead. This decision was based on his feeling that the odds were really in my favor that what he left behind would have any cancer cells.
March 12th will be my 3 month mark since going off Avodart, I will have a PSA test and see where I am at. We know my PSA will rise and hopefully then stabilize based on the tissue left behind.
The next future 3 month PSA test will then confirm if I have a problem and need SRT. We decided to pull the trigger at .4 since we know that some of the base PSA is created by benign tissue.
This will be a well documented case and should give some addition guidence for others that might be having the same issues.
